🎓Workshop on Tuning and Calibration of Earth System Models

Identified as a priority at the first WGCM Forum during the CMIP Community Workshop in Kyoto (March 2026), the workshop will bring together 100–120 international experts to address key challenges in tuning and calibrating Earth System Models, with a focus on advancing the scientific understanding and methodological foundations of climate modelling.

Objectives of the workshop

• Advance the scientific understanding of model tuning and calibration in next-generation ESMs, including process-based evaluation, parameter estimation, and multi-objective calibration
• Identify best practices and emerging methodologies, including machine learning approaches and uncertainty quantification
• Addressing the trade-off between high spatial resolution, high complexity and a large ensemble, depending on the scientific research question
• Foster collaboration and information exchange between established modelling centres and emerging groups
• Strengthen international networks and provide opportunities for early career researchers to engage with leading experts
• Provide a platform to discuss ESM outcomes and prepare for future coordinated experiments
• Contribute to rapid, high-impact publications by mid-2027, leveraging ESM simulations such as CMIP7 and km-scale
• Share development lines for next generation models
